Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77766, here are decompositions:
- 5 + 77761 = 77766
- 19 + 77747 = 77766
- 23 + 77743 = 77766
- 43 + 77723 = 77766
- 47 + 77719 = 77766
- 53 + 77713 = 77766
- 67 + 77699 = 77766
- 79 + 77687 = 77766
Showing the first eight; more decompositions exist.
